What's the deal?! 🤷‍♀️

Thought my period was sure to start yesterday or the day before based on my temp dropping, but I've just had a slight hint of brown colored discharge only when wiping. Got up today and my temp had gone back up....I have no clue what is going on..?? Anyone's chart ever looked like this?! Should I test? I just don't even know anymore...I'm so sick of testing just to see a negative again...

***UPDATE***

Just took my temp for the day. It is down just a little, but still above my coverline. My temp tends to fluctuate a little from day to day, so really this doesn't tell me much. It could be on the way back down or it could just be a normal fluctuation for me. 🤷‍♀️ I think I will buy some tests on my way home from work today and depending on what my temp is like tomorrow morning I may test. Here is my updated chart.
